Update BIOS update page and remove warnings

[Mr-KayZ]

Modern motherboards often have a method to recover from a failed BIOS flash, and considering new security updates and imrpoved memory compatibility for several devices, it might be recommended to update the BIOS now.

Also reword the entire article to make it less of a word salad and easier to read and understand for most people.

However do make it explicitly clear that the user should check if there is a BIOS recovery option for their current motherboard.

Sometimes cheaper/lower end motherboards might not have such options, so it still is risky for them.
